Or if you want to make a new private key with Bip85 what will happen with your followers?
Discussion
can you summarize BIP85?
Basically you can generate other keys from your main seed phrase. That way you can secure them with one metal storage as restoring that one will let you restore the others.
So you could make a Nostr private key, a Phoenix key etc. and only need to back up the original key.
Jade, Passport, and Coldcard all support it.
